The immersive voice module launched by Nuvoton Technology and Beijing Twirling Inc. supports three microphone array Ambisonic sound field acquisition. Ambisonic technology is widely used in immersive audio in recent years. It is the standard audio in VR / AR; it is also gradually supported in broadcasting, filming, and television industries, such as the MPEG-H agreement launched by the global standards organization. Some standards also have been defined in China Broadcasting System. Ambisonic has a powerful mode conversion function, which can simultaneously support traditional mono and dual-channel stereo sound transmission methods and can flexibly support all mainstream immersive audio formats such as 5.1 and 7.1 on the decoding side.
